我们调查形成有序的时空激活池的神经元synfire链（SFC）内的平衡网络，无论是模拟和分析工具。使用一个合适的矩阵的突触连接，我们表明，结果取决于一个单独的池的神经元（W）和神经元的总兴奋性输入（K）的大小之间的比率。在我们对10，000个神经元的模拟中，我们获得了一种异步不规则放电模式，该模式不维持SFC活动的行进脉冲包。我们的分析表明，后者可能存在于较大的网络中，其中可以实现非常小的w/K值。(C)2002 Elsevier Science B. V.保留所有权利。
We investigate the formation of ordered spatiotemporal activations of pools of neurons in synfire chains (SFC) within a balanced network, both by simulations and by analytic tools. Using a suitable matrix of synaptic connections, we show that the results depend on the ratio between the size of an individual pool of neurons (w) and the total excitatory input of a neuron (K). In our simulations of 10,000 neurons, we obtain an asynchronous-irregular firing mode, which does not sustain a traveling pulse-packet of SFC activity. Our analysis shows that the latter may be expected to exist in larger networks in which very small w/K values can be realized. (C) 2002 Elsevier Science B.V. All rights reserved.
